If a disfellowshipped person was to arrive early and wander around the hall quietly or dilly-dally after the song and do the same many would complain, and the elders I have known would likely see it as an act of beligerence on the part of the disfellowshipped one.
I just wish people would wake up and stop submitting to this stupid religion with it's stupid rules.
Why would anyone want to go to a club where no one wanted you, no one spoke to you or even made eye contact. The whole thing is just stupid and discriminatory beyond belief.
